Product Description:

High quality switching 'wall wart' 'wall adapter' AC to DC 3.3V 2A wall power supply. These are switch mode power supplies which mean the output is regulated to 3.3V. They take 100-240Vac 50/60Hz input and output 3.3V 2A (2A is very incredible for its size). These will power most projects that don't require more than 2A of current. Center-negative 5.5x2.1mm barrel connector.

They are design to take up ONE position on your outlet strip or wall outlet. These will convert international voltage (100V-240Vac 50/60Hz) automatically; no transformer needed. The cable is about 4.5 ft. long. There is an LED indicator for supply OK. Great for many electronic projects!
